In mobile telecommunications domain, LTE-4G is currently the most advanced standard available. A major design issue of LTE-4G based systems resides in solving the memory access conflicts when connecting Rate-Matching (RM) and Error Correction Code (ECC) modules. In this paper, we first describe and analyze the problem before proposing a dedicated memory mapping approach. Results show that our method allows removing any conflicts for any block sizes and any parallelism degrees in the context of LTE-4G.
